Interplanetary NASA probe Voyager 1, launched 35 years ago, crossed the heliosphere and became the first artificial object, left the solar system.

This was reported by American scientists in a paper accepted for publication in the journal Geophysical Research Letters.
"It seems that Voyager 1 has left the region, which depends on the exposure to the sun, the data show such characteristics of hydrogen and helium, which are expected to be observed in the interstellar medium," - stated the staff of the University of New Mexico.
The boundary of the solar system is considered heliosphere, filled by the solar wind. Outside begins interstellar space, a property which already does not depend on the magnetic field, or by a stream of charged particles emanating from the sun.
In early December last year, NASA announced that Voyager has entered into a magnetic "fast highway" for charged particles at the edge of the solar system. This was the last leg of the journey to interstellar space probe, which could take anywhere from a few months to a couple of years. The media were quick to report that the probe is outside the solar system, in October last year.
On board the probe sensors, devices, cameras and even a message to extraterrestrial civilizations in the form of gold-plated disc, which marked the coordinates of the Earth, placed images of people and animals, recorded piece of music and human speech.
